DS3400V7000迁移oracle10G

DS3400迁移到V7000（redhat4.7+oracle10GRAC）

一、备份2个raw设备

[root@node1~]#ddif=/dev/raw/raw1of=/root/raw1

2096753+0recordsin

2096753+0recordsout

[root@node2~]#ddif=/dev/raw/raw2of=/root/raw2

2096753+0recordsin

2096753+0recordsout

二、关闭rac所有节点，连接SAN交换机，划分zone，DS3400存储的光纤连接和SVC的光纤连接划为一个zone，主机和SVC划分一个zone

三、SVC接管DS3400存储，导入为临时存储池

DS3400存储更改Mapping为SVC

SVC检测DS3400存储硬盘

导入后的结果

四、所有RAC节点开机，SVC创建主机，映射硬盘

五、redhat4系统卸载DS3400多链路软件RDAC

在RDAC目录运行makeuninstall,修改/boot/grub/menu.lst，重启动系统识别存储硬盘

#boot=/dev/sda

default=0

timeout=5

splashimage=（hd0,0）/grub/splash.xpm.gz

hiddenmenu

titleRedHatEnterpriseLinuxAS（2.6.9-78.ELsmp）

root（hd0,0）

kernel/vmlinuz-2.6.9-78.ELsmproroot=LABEL=/rhgbquiet

initrd/initrd-2.6.9-78.ELsmp.img（initrd/mpp-2.6.9-78.ELsmp.img）

titleRedHatEnterpriseLinuxAS-up（2.6.9-78.EL）

root（hd0,0）

kernel/vmlinuz-2.6.9-78.ELroroot=LABEL=/rhgbquiet

initrd/initrd-2.6.9-78.EL.img

六、配置SVC多链路，修改raw设备对应关系

1、安装linux多链路软件

device-mapper

device-mapper-multipath.

查看rpm–qa|grepmapper

[root@node1~]#rpm-qa|grepmapper

device-mapper-1.02.25-2.el4

device-mapper-multipath-0.4.5-31.el4

device-mapper-1.02.25-2.el4

2、修改/etc/multipath.conf

defaults{

polling_interval30

failbackimmediate

no_path_retryqueue

rr_min_io100

path_checkertur

user_friendly_namesyes

}

#SVC

device{

vendor"IBM"

product"2145"

path_grouping_policygroup_by_prio

prio_callout"/sbin/mpath_prio_alua/dev/%n"

}

操作步骤：

[root@node1etc]#cpmultipath.confmultipath.conf.bak

[root@node1etc]#rmmultipath.conf

rm:

removeregularfile`multipath.conf'?

y

[root@node1etc]#vimultipath.conf

defaults{

polling_interval30

failbackimmediate

no_path_retryqueue

rr_min_io100

path_checkertur

user_friendly_namesyes

}

#SVC

device{

vendor"IBM"

product"2145"

path_grouping_policygroup_by_prio

prio_callout"/sbin/mpath_prio_alua/dev/%n"

}

3、设置开机启动mapper，重启动系统

chkconfigmultipathdon

chkconfig--level345multipathdon

查看设备

multipath–ll

[root@node2~]#multipath-ll

mpath2（3600507680281866b000000000000009b）

4、修改raw对应关系，重启动系统

vi/etc/sysconfig/rawdevices

/dev/raw/raw1/dev/mapper/mpath0p1

/dev/raw/raw2/dev/mapper/mpath1p1

/dev/raw/raw3/dev/mapper/mpath2p1

/dev/raw/raw4/dev/mapper/mpath3p1

/dev/raw/raw5/dev/mapper/mpath4p1

如果启动后权限更改，修改/etc/rc.local

[root@node2~]#cat/etc/rc.local

#!

/bin/sh

#

#Thisscriptwillbeexecuted*after*alltheotherinitscripts.

#Youcanputyourowninitializationstuffinhereifyoudon't

#wanttodothefullSysVstyleinitstuff.

七、svc配置磁盘镜像,镜像完成后拆分镜像，使用新存储的磁盘

镜像完成后，拆分镜像，使用新存储硬盘

使用新的存储硬盘
